A tale of tree cities

by Ayesha Bapasola

 

What single measure has a positive impact on soil erosion, biodiversity loss, health and community spirit? The Urban Orchard Project (UOP) claims that all this and more can be achieved through their community-centred model of promoting sustainable green infrastructure, often in the midst of the hubbub of metropolitan life.

Fit for pigs?

Pig and carrot

by Edd Colbert

 

Pigs are perhaps the original solution to the problem of food waste, but one that current farming practice and legislation has put out to graze. It is likely that their voracious appetite for our leftovers and offcuts was the reason why humans first domesticated pigs, and for centuries they helped to make sure that little went to waste. In the last hundred years, cheap grain reduced pigs’ role as waste disposers, but it was the foot and mouth outbreak in the UK in 2001 that led to swill kicking the bucket.

Playing chicken with the climate: why environmentalists should go veggie

by Francis Vergunst

 

You’ve heard it from the Greens, you’ve heard it from your friends, you’ve probably even heard it from your grandma… and now you’re hearing it from the government too. What’s the big deal? Do we really need to eat less meat – or none at all? I would argue that becoming vegetarian could be the most effective action you take against climate change. Consider the following.

Fed up with the food waste scandal

by Tristram Stuart

 

On Saturday 12th May, Bristol will be the first city outside London to host a Feeding the 5000 (F5K) event. Between 1pm and 5pm, anyone who comes to visit College Green will have the chance to disprove the old adage – there really can be such a thing as a free lunch, thanks to the support of local charities, businesses and volunteers, including some of Bristol’s top chefs such as the Fabulous Baker Brothers, Tom Hunt and the Thali Café.

We can’t afford to waste phosphorus

by Thomas Vergunst

 

Demand for it is expected to rise by at least 50% by 2050. China, Morocco, the US, South Africa and Jordan control 85% of global reserves, which, according to some sources, are only expected to last another 50-100 years. The price in the EU rose by 800% in 2008 and the UK imports over 600,000 tonnes each year, at a cost of over £100m. But this isn’t a fossil fuel or a rare earth metal – it is phosphorus, an essential plant nutrient and an element for which there is no substitute. Therefore, as supplies of rock phosphate start dwindling there will be no possibility for shifting to alternatives – we will be forced to improve both the efficiency with which we extract/use the material and the rate at which we recover it from our waste streams.

Slurry seems to be the hardest word

Peter Jones

by Peter Jones

 

A talk by Helen Browning, CEO of the Soil Association, on 2 November left me pondering the problems of farming and waste.  Helen is a compelling speaker and, despite battling the after-effects of a cold, tackled a lot of topics with energy and thoughtfulness.
